Remove the manifolds for sensors

Removed the two rear exhaust manifolds from the Jabiru to get the holes drilled for the Exhaust Gas Temp (EGT) sensors.

Need to be 100mm down from the manifold.

Also, this is how every self respecting ‘plane builder goes to work .. on his motorbike .. with a Jabiru exhaust stuffed down his front … this is going to have two holes drilled for the smoke atomizers (10″ from the exit hole)
